Epc (also called real mold casting) and casting size shape is similar to that of paraffin wax or foam model binding into clusters, brush after refractory coating and drying, buried in the dry quartz sand vibration model, under the negative pressure casting, make the model of gasification, liquid metal model position, after cooling solidification form a new type of foundry casting method.

 

1. Lost mold casting castings are accurate in size and shape, with good repeatability, and have the characteristics of precision casting;

 

2. High surface finish of casting;

 

3. Lost mold casting eliminates the sand core and core making department, eradicating casting defects and waste products caused by core making and lower core;

 

4. Not fitting the box, not taking the mold, greatly simplifying the molding process, eliminating the casting defects and waste products caused by taking the mold and closing the box;

 

5. Lost mold casting adopts dry sand modeling without binder, moisture and any additives, which eliminates all kinds of casting defects and waste products caused by moisture, additives and adhesives;

 

6. Greatly simplifying the sand treatment system, sand can be repeated all 7. Sand falling is extremely easy, greatly reducing the workload and labor intensity of sand falling;

 

8. There is no flying burr in lost mold casting, which can reduce the cleaning and polishing work by more than 50%;

 

9. The casting riser with reasonable shape can be set in the ideal position, which is not restricted by the traditional factors such as typing and mold taking, and reduces the internal defects of the casting;

 

10. Negative pressure casting is more conducive to the filling and feeding of liquid metal, and improves the microstructure density of the casting;

 

11. Combined casting, more than one box, greatly improve the casting production rate and production efficiency;

 

12. Lost mold casting reduces machining margin and machining cost;

 

13. Easy to realize mechanized automatic production line, production line flexibility, can realize the production of different alloy, different shape, different size castings in one production line;

 

14. Can cancel the drawing inclination;

 

15. The life of the metal mold can reach more than 100,000 times, reducing the maintenance cost of the mold;

 

16. Lost mold casting reduces dust, smoke and noise pollution, greatly improves the working environment of foundry workers, reduces the labor intensity, and the industry dominated by male workers can become the industry dominated by female workers;

 

17. The process operation is simplified, and the technical proficiency of workers is greatly reduced;

 

18. The shape of the parts is not restricted by the traditional casting process, freeing the mechanical design workers, so that according to the performance of the parts, they can freely design the ideal casting shape;

 

19. Lost mold casting can reduce casting weight;

 

20. Reduced production cost;

 

21 Simplified plant design, fixed asset investment can be reduced by 30∽40%, land area and building area can be reduced by 30∽50%, and power consumption can be reduced by 10∽20%;

 

22. Lost mold casting process is widely used, not only for casting steel, cast iron, more suitable for casting copper, aluminum, etc.;

 

23. Lost mold casting process is not only suitable for simple geometric shapes of castings, more suitable for ordinary casting difficult to start the multi-edge, multi-core, complex geometric shapes of castings;

 

24. Lost mold casting process can realize the casting under the state of microseismic, promote the formation of special requirements of the metallographic structure, is conducive to improve the inherent quality of the casting;

 

25. Combined casting in dry sand is easy to desander and the temperature is synchronized, so waste heat can be used for heat treatment. Especially the water edge treatment of high manganese steel castings and the solution treatment of heat resistant steel castings, the effect is very ideal, can save a lot of energy, shorten the processing cycle;

 

26. By using the lost mold casting process, castings of any size can be completed according to the melting capacity.

 

27. Lost mold casting is suitable for group casting, dry sand buried desanding is easy, in some material castings can also be used according to the waste heat treatment. Use, cancel the molding sand preparation department and waste sand treatment department;
